摘要: 棉花形态性状对于棉株营养生长至关重要,同时,对其生殖生长也有着关键影响。该研究对来源于3个不同种植环境下的39个陆地棉品种材料及其178个F1组合的株高、茎秆粗、第一果节数和果枝数的遗传结构进行了剖析。关联分析采用基于混合线性模型的统计方法,剖析的遗传效应包括加性效应、显性效应、上位性效应及其与环境的互作效应。结果共检测到25个数量性状SSR(simple sequence repeat,简单重复序列)位点与这4个形态学性状显著相关,总遗传率达到63.08%~78.28%;加性、显性及其与环境的互作效应是棉花形态性状遗传的重要遗传资源,直接选择显著的SSR位点可优化棉株的形态性状。
Abstract: Morphological traits played an important role in vegetative growth of cotton (Gossypium hirsutum L.), and also had an critical impact on reproductive growth. In this study, we dissected the genetic architecture of four morphological traits, including plant height (PLH), stem diameter (STD), stem first (STF) and stem node (STN). Thirty-nine lines and their 178 F1 hybrids of upland cotton grown in three environments were used for association mapping. The association mapping was conducted using mixed linear model approaches for analyzing full genetic model with genetic effects of additive, dominance, epistasis and their environment interaction. The results showed that 25 highly significant quantitative trait SSRs (QTSs) were detected and their total heritability was high for the four morphological traits studied (h2G+GE≈63.08%78.28%). It was revealed that additive, dominance and their environment interaction effects were important genetic recourses for morphological traits in cotton. This research provides new insights into cotton quantitative genetics and molecular breeding.
